E.g. "far-away.east:0". +Port numbers are also allowed, e.g. far-away.east:5905. + +Or supply user@hostname:display and click on the "Use SSH" option, then +press the "Connect" button to connect to the server via an SSH tunnel. +E.g.

It can connect to any VNC\-compatible server such +as \fBXvnc\fR, WinVNC, or \fBx11vnc\fR, allowing you to control desktop environment +of a different machine. + +ssvncviewer is an enhanced version of the tightvnc unix viewer that can +take advantage of features in the \fBx11vnc\fR and UltraVNC VNC servers. +See below for the description of these features. + +You can use F8 to display a pop\-up utility menu. Press F8 twice to +pass single F8 to the remote side. +.SH OPTIONS +.TP +\fB\-help\fR +Prints a short usage notice to stderr. +.TP +\fB\-listen\fR +Make the viewer listen on port 5500+\fIdisplay\fR for reverse +connections from a server. WinVNC supports reverse connections using +the "Add New Client" menu option, or the \-connect command line +option. \fBXvnc\fR requires the use of the helper program +\fBvncconnect\fR. +.TP +\fB\-via\fR \fIgateway\fR +Automatically create encrypted TCP tunnel to the \fIgateway\fR machine +before connection, connect to the \fIhost\fR through that tunnel +(TightVNC\-specific). By default, this option invokes SSH local port +forwarding, assuming that SSH client binary can be accessed as +/usr/bin/ssh. Note that when using the \fB\-via\fR option, the host +machine name should be specified as known to the gateway machine, e.g. +"localhost" denotes the \fIgateway\fR, not the machine where vncviewer +was launched. See the ENVIRONMENT section below for the information on +configuring the \fB\-via\fR option. +.TP +\fB\-shared\fR +When connecting, specify that a shared connection is requested. In +TightVNC, this is the default mode, allowing you to share the desktop +with other clients already using it. +.TP +\fB\-noshared\fR +When connecting, specify that the session may not be shared. This +would either disconnect other connected clients or refuse your +connection, depending on the server configuration. +.TP +\fB\-viewonly\fR +Disable transfer of mouse and keyboard events from the client to the +server. +.TP +\fB\-fullscreen\fR +Start in full\-screen mode. Please be aware that operating in +full\-screen mode may confuse X window managers. Typically, such +conflicts cause incorrect handling of input focus or make the viewer +window disappear mysteriously. See the grabKeyboard setting in the +RESOURCES section below for a method to solve input focus problem. +.TP +\fB\-noraiseonbeep\fR +By default, the viewer shows and raises its window on remote beep +(bell) event. This option disables such behaviour +(TightVNC\-specific). +.TP +\fB\-user\fR \fIusername\fR +User name for Unix login authentication. Default is to use current +Unix user name. If this option was given, the viewer will prefer Unix +login authentication over the standard VNC authentication. +.TP +\fB\-passwd\fR \fIpasswd\-file\fR +File from which to get the password (as generated by the +\fBvncpasswd\fR(1) program). This option affects only the standard VNC +authentication. +.TP +\fB\-encodings\fR \fIencoding\-list\fR +TightVNC supports several different compression methods to encode +screen updates; this option specifies a set of them to use in order of +preference. Encodings are specified separated with spaces, and must +thus be enclosed in quotes if more than one is specified. Available +encodings, in default order for a remote connection, are "copyrect +tight hextile zlib corre rre raw". For a local connection (to the same +machine), the default order to try is "raw copyrect tight hextile zlib +corre rre". Raw encoding is always assumed as a last option if no +other encoding can be used for some reason. For more information on +encodings, see the section ENCODINGS below. +.TP +\fB\-bgr233\fR +Always use the BGR233 format to encode pixel data. This reduces +network traffic, but colors may be represented inaccurately. The +bgr233 format is an 8\-bit "true color" format, with 2 bits blue, 3 +bits green, and 3 bits red. +.TP +\fB\-owncmap\fR +Try to use a PseudoColor visual and a private colormap. This allows +the VNC server to control the colormap. +.TP +\fB\-truecolour\fR, \fB\-truecolor\fR +Try to use a TrueColor visual. +.TP +\fB\-depth\fR \fIdepth\fR +On an X server which supports multiple TrueColor visuals of different +depths, attempt to use the specified one (in bits per pixel); if +successful, this depth will be requested from the VNC server. +.TP +\fB\-compresslevel \fIlevel\fR +Use specified compression \fIlevel\fR (0..9) for "tight" and "zlib" +encodings (TightVNC\-specific). Level 1 uses minimum of CPU time and +achieves weak compression ratios, while level 9 offers best +compression but is slow in terms of CPU time consumption on the server +side. Use high levels with very slow network connections, and low +levels when working over high\-speed LANs. It's not recommended to use +compression level 0, reasonable choices start from the level 1. +.TP +\fB\-quality \fIlevel\fR +Use the specified JPEG quality \fIlevel\fR (0..9) for the "tight" +encoding (TightVNC\-specific). Quality level 0 denotes bad image +quality but very impressive compression ratios, while level 9 offers +very good image quality at lower compression ratios. Note that the +"tight" encoder uses JPEG to encode only those screen areas that look +suitable for lossy compression, so quality level 0 does not always +mean unacceptable image quality. +.TP +\fB\-nojpeg\fR +Disable lossy JPEG compression in Tight encoding (TightVNC\-specific). +Disabling JPEG compression is not a good idea in typical cases, as +that makes the Tight encoder less efficient. You might want to use +this option if it's absolutely necessary to achieve perfect image +quality (see also the \fB\-quality\fR option). +.TP +\fB\-nocursorshape\fR +Disable cursor shape updates, protocol extensions used to handle +remote cursor movements locally on the client side +(TightVNC\-specific). Using cursor shape updates decreases delays with +remote cursor movements, and can improve bandwidth usage dramatically. +.TP +\fB\-x11cursor\fR +Use a real X11 cursor with X-style cursor shape updates, instead of +drawing the remote cursor on the framebuffer. This option also +disables the dot cursor, and disables cursor position updates in +non-fullscreen mode. +.TP +\fB\-autopass\fR +Read a plain-text password from stdin. This option affects only the +standard VNC authentication. + +.SH Enhanced TightVNC Viewer (SSVNC) OPTIONS +.TP +Enhanced TightVNC Viewer (SSVNC) web page is located at: +.TP +http://www.karlrunge.com/x11vnc/ssvnc.html +.TP +Note: ZRLE and ZYWRLE encodings are now supported. +.TP +Note: F9 is shortcut to Toggle FullScreen mode. +.TP +Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1 +to allow more than one incoming VNC server at a time. +.TP +Note: If the host:port is specified as "exec=command args..." +then instead of making a TCP/IP socket connection to the +remote VNC server, "command args..." is executed and the +viewer is attached to its stdio. This enables tunnelling +established via an external command, e.g. an stunnel(8) +that does not involve a listening socket. +This mode does not work for -listen reverse connections. +.TP +Note: If the host:port contains a '/' it is interpreted as a +unix-domain socket (AF_LOCAL insead of AF_INET) +.TP +\fB\-use64\fR +In \fB\-bgr233\fR mode, use 64 colors instead of 256. +.TP +\fB\-bgr222\fR +Same as \fB\-use64\fR. +.TP +\fB\-use8\fR +In \fB\-bgr233\fR mode, use 8 colors instead of 256. +.TP +\fB\-bgr111\fR +Same as \fB\-use8\fR. +.TP +\fB\-16bpp\fR +If the vnc viewer X display is depth 24 at 32bpp +request a 16bpp format from the VNC server to cut +network traffic by up to 2X, then tranlate the +pixels to 32bpp locally. +.TP +\fB\-bgr565\fR +Same as \fB\-16bpp\fR. +.TP +\fB\-grey\fR +Use a grey scale for the 16- and 8\fB\-bpp\fR modes. +.TP +\fB\-alpha\fR +Use alphablending transparency for local cursors +requires: x11vnc server, both client and server +must be 32bpp and same endianness. +.TP +\fB\-ycrop\fR n +Only show the top n rows of the framebuffer. For +use with x11vnc \fB\-ncache\fR client caching option +to help "hide" the pixel cache region. +Use a negative value (e.g. \fB\-1\fR) for autodetection. +Autodetection will always take place if the remote +fb height is more than 2 times the width. +.TP +\fB\-sbwidth\fR n +Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR), +default is very narrow: 2 pixels, it is narrow to +avoid distraction in \fB\-ycrop\fR mode. +.TP +\fB\-nobell\fR +Disable bell. +.TP +\fB\-rawlocal\fR +Prefer raw encoding for localhost, default is +no, i.e. assumes you have a SSH tunnel instead. +.TP +\fB\-graball\fR +Grab the entire X server when in fullscreen mode, +needed by some old window managers like fvwm2. +.TP +\fB\-popupfix\fR +Warp the popup back to the pointer position, +needed by some old window managers like fvwm2. +.TP +\fB\-grabkbd\fR +Grab the X keyboard when in fullscreen mode, +needed by some window managers. Same as \fB\-grabkeyboard\fR. +\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable. +.TP +\fB\-bs\fR, \fB\-nobs\fR +Whether or not to use X server Backingstore for the +main viewer window. The default is to not, mainly +because most Linux, etc, systems X servers disable +*all* Backingstore by default. To re\fB\-enable\fR it put +Option "Backingstore" +in the Device section of /etc/X11/xorg.conf. +In \fB\-bs\fR mode with no X server backingstore, whenever an +area of the screen is re\fB\-exposed\fR it must go out to the +VNC server to retrieve the pixels. This is too slow. +In \fB\-nobs\fR mode, memory is allocated by the viewer to +provide its own backing of the main viewer window. This +actually makes some activities faster (changes in large +regions) but can appear to "flash" too much. +.TP +\fB\-noshm\fR +Disable use of MIT shared memory extension (not recommended) +.TP +\fB\-termchat\fR +Do the UltraVNC chat in the terminal vncviewer is in +instead of in an independent window. +.TP +\fB\-unixpw\fR +str Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a +string that allows many ways to enter the Unix Username +and Unix Password. These characters: username, newline, +password, newline are sent to the VNC server after any VNC +authentication has taken place. Under x11vnc they are +used for the \fB\-unixpw\fR login. Other VNC servers could do +something similar. +You can also indicate "str" via the environment +variable SSVNC_UNIXPW. +Note that the Escape key is actually sent first to tell +x11vnc to not echo the Unix Username back to the VNC +viewer. Set SSVNC_UNIXPW_NOESC=1 to override this. +If str is ".", then you are prompted at the command line +for the username and password in the normal way. If str is +"-" the stdin is read via getpass(3) for username@password. +Otherwise if str is a file, it is opened and the first line +read is taken as the Unix username and the 2nd as the +password. If str prefixed by "rm:" the file is removed +after reading. Otherwise, if str has a "@" character, +it is taken as username@password. Otherwise, the program +exits with an error. Got all that? +.TP +\fB-repeater\fR str This is for use with UltraVNC repeater proxy described +here: http://www.uvnc.com/addons/repeater.html. The "str" +is the ID string to be sent to the repeater. E.g. ID:1234 +It can also be the hostname and port or display of the VNC +server, e.g. 12.34.56.78:0 or snoopy.com:1. Note that when +using -repeater, the host:dpy on the cmdline is the repeater +server, NOT the VNC server. The repeater will connect you. +Example: vncviewer ... -repeater ID:3333 repeat.host:5900 +Example: vncviewer ... -repeater vhost:0 repeat.host:5900 +.TP +\fB\-printres\fR Print out the Ssvnc X resources (appdefaults) and +then exit. You can save them to a file and customize them (e.g. the +keybindings and Popup menu) Then point to the file via +XENVIRONMENT or XAPPLRESDIR. +.TP +\fB New Popup actions:\fR + + ViewOnly: ~ -viewonly + Disable Bell: ~ -nobell + Cursor Shape: ~ -nocursorshape + X11 Cursor: ~ -x11cursor + Cursor Alphablend: ~ -alpha + Toggle Tight/ZRLE: ~ -encodings ... + Toggle ZRLE/ZYWRLE: ~ -encodings zywrle... + Quality Level ~ -quality (both Tight and ZYWRLE) + Compress Level ~ -compresslevel + Disable JPEG: ~ -nojpeg (Tight) + Full Color ~ as many colors as local screen allows. + Grey scale (16 & 8-bpp) ~ -grey, for low colors 16/8bpp modes. + 16 bit color (BGR565) ~ -16bpp / -bgr565 + 8 bit color (BGR233) ~ -bgr233 + 256 colors ~ -bgr233 default # of colors. + 64 colors ~ -bgr222 / -use64 + 8 colors ~ -bgr111 / -use8 + Set Y Crop (y-max) ~ -ycrop + Set Scrollbar Width ~ -sbwidth + + UltraVNC Extensions: + + Set 1/n Server Scale Ultravnc ext.

The most common +formats are 24 and 16 bit "true\-color" values, and 8\-bit "color map" +representations, where an arbitrary map converts the color number to +RGB values. + +.I Encoding +refers to how a rectangle of pixels are sent (all pixel information in +VNC is sent as rectangles). All rectangles come with a header giving +the location and size of the rectangle and an encoding type used by +the data which follows. These types are listed below. +.TP +.B Raw +The raw encoding simply sends width*height pixel values. All clients +are required to support this encoding type. Raw is also the fastest +when the server and viewer are on the same machine, as the connection +speed is essentially infinite and raw encoding minimizes processing +time. +.TP +.B CopyRect +The Copy Rectangle encoding is efficient when something is being +moved; the only data sent is the location of a rectangle from which +data should be copied to the current location. Copyrect could also be +used to efficiently transmit a repeated pattern. +.TP +.B RRE +The Rise\-and\-Run\-length\-Encoding is basically a 2D version of +run\-length encoding (RLE). In this encoding, a sequence of identical +pixels are compressed to a single value and repeat count. In VNC, this +is implemented with a background color, and then specifications of an +arbitrary number of subrectangles and color for each. This is an +efficient encoding for large blocks of constant color. +.TP +.B CoRRE +This is a minor variation on RRE, using a maximum of 255x255 pixel +rectangles. This allows for single\-byte values to be used, reducing +packet size. This is in general more efficient, because the savings +from sending 1\-byte values generally outweighs the losses from the +(relatively rare) cases where very large regions are painted the same +color. +.TP +.B Hextile +Here, rectangles are split up in to 16x16 tiles, which are sent in a +predetermined order. The data within the tiles is sent either raw or +as a variant on RRE. Hextile encoding is usually the best choice for +using in high\-speed network environments (e.g. Ethernet local\-area +networks). +.TP +.B Zlib +Zlib is a very simple encoding that uses zlib library to compress raw +pixel data. This encoding achieves good compression, but consumes a +lot of CPU time. Support for this encoding is provided for +compatibility with VNC servers that might not understand Tight +encoding which is more efficient than Zlib in nearly all real\-life +situations. +.TP +.B Tight +Like Zlib encoding, Tight encoding uses zlib library to compress the +pixel data, but it pre\-processes data to maximize compression ratios, +and to minimize CPU usage on compression. Also, JPEG compression may +be used to encode color\-rich screen areas (see the description of +\-quality and \-nojpeg options above). Tight encoding is usually the +best choice for low\-bandwidth network environments (e.g. slow modem +connections). +.TP +.B ZRLE +The SSVNC viewer has ported the RealVNC (www.realvnc.com) ZRLE encoding +to the unix tightvnc viewer. +.TP +.B ZYWRLE +The SSVNC viewer has ported the Hitachi lossy wavelet based ZRLE +encoding from http://mobile.hitachi-system.co.jp/publications/ZYWRLE/ +to the unix tightvnc viewer. +.SH RESOURCES +X resources that \fBvncviewer\fR knows about, aside from the +normal Xt resources, are as follows: +.TP +.B shareDesktop +Equivalent of \fB\-shared\fR/\fB\-noshared\fR options.
